Detailed implementation manners

[0020] To further elaborate on the technical means and effects adopted by the present utility model to achieve the intended utility model purpose, the following, in conjunction with the attached drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the present utility model as follows.

[0021] Embodiment: Please refer to Figures 1-4 , a putty powder mixer, comprising a motor 1, a rotating shaft 11, and a mixing tank 5.

[0022] The motor 1 is fixedly connected to the top of the mixing tank 5, and the rotating shaft 11 is located inside the mixing tank 5 and fixedly connected to the output end of the motor 1. Horizontally fixedly connected to the rotating shaft 11 are stirring rods 111, and there are multiple stirring rods 111 arranged from top to bottom. At the lower end of the rotating shaft 11 is a stirring head 112. The stirring head 112 can adopt existing technologies. In this embodiment, the stirring head 112 includes multiple short rods and a connecting ring fixedly connecting these multiple short rods. The short rods are arranged obliquely downward and the upper ends are fixedly connected to the rotating shaft 11. After the motor 1 is started, it drives the rotating shaft 11 to rotate, so that the stirring rods 111 and the stirring head 112 rotate for stirring. The stirring head 112 serves to supplement the stirring of the materials at the bottom of the mixing tank 5.

[0023] At the top of the mixing tank 5 is a feeding port, and the feeding port includes a water inlet 2, a main material port 3, and a minor material port 4, which are respectively used for feeding water, main materials, and minor materials. The rotating shaft 11 is fixedly connected with a sieve plate 52. The sieve plate 52 is located above the stirring rods 111. Above the sieve plate 52 and between the rotating shaft 11 and the inner wall of the mixing tank 5, a scraping plate 511, a pressing roller 512, and a brush 513, which are respectively fixedly connected to the mixing tank 5, are sequentially arranged. When the rotating shaft 11 rotates, the sieve plate 52 also rotates. The materials on the sieve plate 52 are first leveled under the action of the scraping plate 511, and then rolled under the action of the pressing roller 512. After being rolled, the materials are brushed up by the brush of the brush 513 and then fall through the sieve plate 52 to the lower part of the sieve plate 52 for stirring.

[0024] Further, in this embodiment, a partition ring 51 is provided above the sieve plate 52. The upper end of the partition ring 51 is fixedly connected to the top of the mixing tank 5, and the lower end of the partition ring 51 is in clearance fit with the sieve plate 52. The scraping plate 511, the pressing roller 512, and the brush 513 are fixedly connected to the partition ring 51 and thus fixedly connected to the mixing tank 5. In other specific embodiments without the partition ring 51, the diameter of the sieve plate 52 is slightly smaller than or equal to the inner diameter of the mixing tank 5, so that the material and water can enter the lower part for mixing only after passing through the sieve plate 52. In this embodiment, the diameter of the sieve plate 52 is larger than the diameter of the partition ring 51 and smaller than the inner diameter of the mixing tank 5. An injection plate 53 is provided between the partition ring 51 and the inner wall of the mixing tank 5. The injection plate 53 is fixedly connected to the mixing tank 5 and the partition ring 51 respectively. An annular groove 531 is provided on the injection plate 53. The water inlet 2 is located between the partition ring 51 and the inner wall of the mixing tank 5, and the main material inlet 3 and the minor material inlet 4 are located between the partition ring 51 and the rotating shaft 11. The main material and minor material of the material can enter the lower part for mixing only after passing through the sieve plate 52, and the water enters the lower part for mixing through the annular groove 531 on the injection plate 53.

[0025] A discharge port is provided at the lower end of the mixing tank 5. An electromagnetic valve is provided at the discharge port, which is not shown in the figure and can be implemented by using the prior art. The discharge port is connected to the feeding port of the screw conveyor 6, so that the putty powder obtained by mixing can be directly conveyed to other processes.

[0026] A viscometer is installed on the side wall of the mixing tank 5, and the installation method can adopt the prior art, which is convenient to know the viscosity of the putty powder.

[0027] The working principle of this embodiment: A putty powder mixer provided in this embodiment. The main material and minor material enter the sieve plate 52 inside the partition ring 51. After the motor 1 is started, the main material and minor material rotate with the sieve plate 52, are leveled under the action of the scraping plate 511, and then are rolled under the action of the pressing roller 512. The rolled material is brushed up by the brush 513 of the brush and then falls through the sieve plate 52 to the lower part of the sieve plate 52 for mixing. Therefore, the caked main material and minor material can be filtered and processed, avoiding the influence of the caked raw materials on the uniformity of subsequent mixing and improving the product quality. The water enters between the partition ring 51 and the inner wall of the mixing tank 5 and enters the lower part to participate in the mixing through the annular groove 531 on the injection plate 53, which has the function of facilitating the flushing of the main material and minor material attached to the inner wall of the mixing tank 5 and is also convenient for cleaning the mixing tank 5. The viscometer is convenient to know the viscosity of the putty powder, and the putty powder obtained by mixing can be directly conveyed to other processes through the screw conveyor 6.
